“…The methodology used to perform this study was developed based on reported works. The determination of wastewater quality, the reuse alternatives selection, the social acceptance, the techno-economic feasibility, health and environmental effects, local regulation among other factors are usually considered in the strategies for treated wastewater management [4,7,9,10,36]. Most of these factors were taken into account to adapt reported frameworks to the case of study.…”

This paper presents an assessment of three potential applications of municipal treated wastewater in a semiarid region of northern Mexico. The potential applications considered are agriculture, industry, and watering urban green areas. The results indicate that in the best scenario, the maximal application of treated wastewater is 150 L/s for industrial activities. Besides industrial applications, this scenario would allow farmers and urban green areas to receive 980 L/s and 70 L/s of treated wastewater respectively. Other issues and alternatives are also identified. With the implementation of this scenario, it is possible to improve the environmental, and even the socioeconomic conditions, of the study region.

“…Due to the superiority of the ER approach in dealing with uncertain evaluations, Zhang and Deng [23] and Dong et al [24] used the evidence theory to analysis fault diagnosis problems in uncertain environment. Akhoundi et al [25] used the ER approach to sustainability evaluation of wastewater reuse alternatives. Ng and Law [26] used ER to analysis sentiment words in social networks to investigate consumer preferences.…”

The evidential reasoning (ER) approach has been widely applied to aggregate evaluation information in multi-expert multicriterion decision-making (MEMCDM) problems with uncertainties. However, the comprehensive results derived by the ER approach remain uncertain. In this study, we propose a Deng-entropy-based ER approach for MEMCDM problems to reduce the uncertainty. Firstly, we reassign the remaining belief of the uncertain evaluation information to the focal elements of the given evaluations. Afterward, we introduce the Deng entropy to respectively calculate the objective weights of criteria and those of experts, so as to reduce the subjective uncertainty in MEMCDM. Then, the ER approach is applied twice to generate the comprehensive evaluations of alternatives. A method is introduced to rank alternatives corresponding to their comprehensive evaluations, forming a Deng-entropy-based ER approach for MEMCDM problems with uncertainty. An illustrative example of screening the people at high risk of lung cancer is provided, and comparative analyses are given to show the rationality and superiority of the proposed method.

“…Therefore, alternative approaches must be sought and incorporated into traditional water management practices to ensure sustainable agricultural production from these water-scarce environments. One suitable and sustainable approach to agricultural production in water-scarce regions is the utilization of alternative water resources in the form of the large quantity of wastewater generated from municipalities [3][4][5][6][7][8][9]. The benefits of utilizing reclaimed wastewater are multiple, in that it provides a reliable year-round source of water for crop production [3], crop yield optimization through the provision of nutrients such as N, P, and K [9][10][11], reduced demand on fossil fuel for synthetic fertilizer production, minimize fertilizer input cost [3], increase crop farm profit margins [12], and enhance environmental conservation due to a reduction in synthetic fertilizer use [13].…”

Grass–Legume Forage Systems Effect on Phosphorus Removal from a Grassland Historically Irrigated with Reclaimed Wastewater

The utilization of reclaimed wastewater is a suitable and sustainable approach to agriculture production in water-scarce regions. However, even though the wastewater is treated to reduce nutrient concentration such as phosphorus, the 10,600 to 14,006 m3 of water applied ha−1 year−1 on grass and alfalfa hay crops in Nevada can lead to soil phosphorus buildup over an extended period. This study evaluated the effectiveness of forage systems (FS) of monoculture grass, monoculture legume, and their mixtures on herbage accumulation, tissue phosphorus concentration, and quantity of phosphorus removed from a grassland under wastewater irrigation. The study was carried out at the Main Station Field laboratory in Reno, Nevada, USA. A total of 23 FS using tall fescue (Schedonorus arundinaceus (Schreb.) Dumort), alfalfa (Medicago sativa L.), red clover (Trifolium pratense L.) and white clover (Trifolium repens L.) in monocultures or grass–legume mixtures (25:75, 50:50, and 75:25) based on seeding rate were used. The response variables were herbage accumulation (HA), tissue phosphorus concentration, and phosphorus removal. Forage systems means were considered different P ≤ 0.05. Herbage accumulation, tissue phosphorus concentration, and phosphorus removal differed among FS and year. Herbage accumulation was similar for the grass monocultures (10.5 Mg ha−1; SE = 1.1) and the majority of the grass–legume mixtures (9.0 Mg ha−1; SE = 1.1) but both systems had greater HA than legumes monoculture (4.3 Mg ha−1; SE = 1.1). The legume monocultures of alfalfa and white clover had the greatest phosphorus concentrations (10.9 g kg−1 dry matter; SE = 0.44) among all FS. Total phosphorus removed was least among legume monocultures (34.0 kg P ha−1; SE = 6.2) in this study and generally similar for grass monocultures (67.4 kg P ha−1; SE = 6.2) and grass–legume mixtures of 75:25 (61.7 kg P ha−1; SE = 6.2). Based on the response variables, agronomic, and environmental considerations a grass–legume mixture that includes 75:25 or even a 50:50 seeding rate ratio will be suitable options for phosphorus removal from phosphorus enriched grasslands in semiarid ecosystems that utilized wastewater for irrigation.
